Abstract

The U.S. Geological Survey (USGS) Groundwater Resources Program began two regional studies in the southeastern United States in the fall of 2009 to investigate ground-water availability of fresh and brackish water resources: (1) groundwater availability of the Floridan aquifer system, (http://water.usgs.gov/ogw/gwrp/activities/regional.html), and (2) saline water aquifer mapping in the southeastern United States. A common goal for both studies was to gather available geophysical logs and related data from the State geological surveys and the USGS that would be used as a basis for developing a hydrogeologic framework for the study area. Similar efforts were undertaken by the USGS Floridan and Southeastern Coastal Plain Regional Aquifer-System Analysis (RASA) Program from the 1970s to mid-1990s (Miller, 1986; Renken, 1996). The logs compiled for these older efforts were difficult to access from the paper files; however, and partly because of this, older and newer logs were compiled into a single digital database for the current study. The purpose of this report is to summarize the different types of logs and related data contained in the database and to provide these logs in a digital format that can be accessed online through the database and files accompanying this report (http://pubs.usgs.gov/ds/760/).
